Well, its not official. But for the 8th game at Evo, the guys behind it have put it up to the community with a pay-to-vote system, of which the proceeds will go to a Breast Cancer foundation. MLP is just one of the entrees at this point, seeing as it only started a few hours ago.

It's a fan-made game, and fans of this "new generation" of My Little Pony, disregard being seemingly intended for little girls, actually are adult males (mostly geeks and nerds). So a MLP fighting game isn't that weird.

PS: You guys should try to see My Little Pony: Friendship is Magic. It's from the same creator from Powerpuff Girls and Mansion Foster, and believe me: It's pretty good. Obviously it isn't as "deep" as, idk, The Walking Dead or Game of Thrones, but if you find yourself bored and want to see a quality light hearted show, you wont be dissapointed.
